Study On Network Remote Monitor Technology Of Open Architecture NC System Based On Windows

In China, most popular NC system at present have no network function or can realize some simple network functions only yet, for instance transmission and save of the network file. And mostly based on DOS platform, the interface isn't intuitional enough and operation isn't easy.The paper is written on purpose of solving the problems mentioned above. The main content of the research include: using Ethernet technology to built up a network remote monitor system and applying it on open architecture NC system. This system use C/S mode to establish the network remote monitor platform, and adopt Windows Socket programming technology based on MFC, Multi-Thread programming technology to develop the systematic network monitoring software based on Windows platform.Through debugging, this network monitoring system has already been succeeded in realizing: (1) network communication function, data exchange function between server and client of the NC system; (2) the Control to systematic processing course in quasi-real time and the control to the system operation interface of NC; (3) Manage file of NC system and offer NC code file to download for NC.There are two innovations in this paper. (1) Have designed a kind of new control algorithm. Its basic thinking is Transmit the real-time coordinates of the processing stand through Ethernet at first, but not transmit the huge processing on-the-spot picture data, Have overcome Windows and Ethernet'sinherent weak real-time character shortcoming, then utilize these real-time coordinates to simulate the trace of processing in the monitor PC. With the algorithm, we have realized the control to NC in quasi-real time; (2) Have adopt segment transmission method, solved large-scale even ultra large-scale NC code file reliable transmission problem among network.
